Abstract
The resin current collector of the present disclosure includes a base material resin, a conductive resin layer including a conductive filler dispersed in the base material resin, and a fluorine-based resin layer laminated on the conductive resin layer. Further, in the use of the resin current collector in the laminated battery, the current collector of at least one end face of the laminated battery is the resin current collector of the present disclosure, and the conductive resin layer is in contact with the other layer constituting the laminated battery, and the fluorine-based resin layer is disposed so as to face the opposite side to the other layer constituting the laminated battery.
Claims19
A resin current collector comprising:
- a conductive resin layer containing a base material resin and a conductive filler dispersed in the base material resin;
- and
- a fluorine-based resin layer laminated on the conductive resin layer, the fluorine-based resin layer including more than 50% by mass of fluorine-based resin.
A laminated battery comprising one or more unit batteries, wherein:
- a resin current collector is provided as an end surface of the laminated battery, the resin current collector comprising:
- a conductive resin layer containing a base material resin and a conductive filler dispersed in the base material resin;
- and
- a fluorine-based resin layer laminated on the conductive resin layer;
- and
- wherein the conductive resin layer of the resin current collector is in contact with another layer of one of the one or more unit batteries constituting the laminated battery, and the fluorine-based resin layer of the resin current collector is disposed so as to face opposite to the another layer of the one of the one or more unit batteries constituting the laminated battery.
A laminated battery comprising:
- a unit battery having of a positive electrode layer, a solid electrolyte layer, and a negative electrode layer;
- a conductive resin layer containing a base material resin and a conductive filler dispersed in the base material resin, the conductive resin layer in contact with the positive electrode layer or the negative electrode layer;
- and
- a fluorine-based resin layer laminated on the conductive resin layer opposite the positive electrode layer or the negative electrode layer in contact with the conductive resin layer.
